The 24-year-old actor will make his west end debut in Mojo as Sweets in the black comedy. Sweets “pops amphetamines like Smarties and does a sort of double act, full of comic menace” with Potts, who will be played by Daniel Mays.

Mojo is a fast-paced gangster plot where would-be rock ‘n’ roll star ‘Silver Johnny’, on the road to fame and fortune during the summer of 1958, encounters problems with his jealous manager, Ezra, the owner of the Atlantic Club, who is hell-bent on protecting him from the amorous advances of creepy local gangster/entrepreneur Sam Ross.
